He's on Duty is a 2010 South Korean 2010 black comedy film that comically yet incisively depicts racial issues in Korea. Tae-sik finds it difficult to get a job due to his odd appearance and impatient character. After failing repeatedly, he disguises himself as a foreigner and finally lands a job. Tae-sik, however, witnesses the cruel treatment migrant workers face in Korea.

Plot

Bang Tae-sik is perennially unemployed as he drifts from one job to another, from manual labor to serving coffee. His appearance (dark skin and short height), being rather atypical for a Korean is to blame it seems, but best buddy Yong-cheol persuades Tae-sik to make better use of these disadvantages: Desperate and having nothing better to do, he adopts a strange accent and ethnic hat and is reborn as Bang-ga (a twist on his family name) from Bhutan, and immediately lands a job at a chair manufacturing factory.
